Blackberries and raspberries belong to the same genus, and it can be hard to tell the difference between the two. It's not surprising that this confusion exists, because there are black raspberries and red blackberries, and both species vary wildly in matters such as leaves, thorns, and appearance of fruit. However, raspberries when picked leave a hard white cone behind; whereas blackberries when picked come away with the receptacle containing the juicy bits (druplets) intact. Blackberries are called bramble bushes in the U.K., and mulberries in France --- and these names persist in the U.S. While there are many kinds of blackberries native to the U.S., the Himalayan blackberries growing wild all over the U.S are not native, nor are Oregon evergreen or cutleaf blackberries, which are thought to have originated in England, arriving in the Pacific Northwest via the South Seas. Altogether, more than 2,000 varieties of blackberries abound in the U.S., whether as cultivated hybrids or as naturally-occurring varietals â€“ A concentrate is a form of substance which has had the majority of its base component, or solvent, removed. Typically this will be the removal of water from a solution or suspension such as the removal of water from fruit juice. The benefit of producing a concentrate is that of a reduction in weight for transportation as the concentrate can be re-constituted at the time of usage Source: foodfacts.com
